Short Answer

Expert verified


The products of the reactions with organometallic reagents are shown below:-

Step by step solution

01

Function of Grignard reagent

When Mg is used, it gets inserted into the carbon-halogen bond to form the Grignard reagent and functions as a nucleophilic agent and also as a base.

When used in excess, it undergoes further reactions with the acid derivatives to form alcohols.They even attack the electrophilic carbon center of carbon dioxide to form carboxylic acids.

02

Product formation

03

 Step 3: Function of organocuprate reagent

When Cu is used, it gets inserted into the carbon-carbon bond to form the organocuprate reagent and functions as a nucleophilic agent by opening the epoxide ring. It also takes part in 1,4-addition reactions.

Product formed from Organocuprate reagent in reaction (e)
